    The references are an important component of any scientific publication. Accuracy of references is essential for providing credibility to the manuscript, authors and journal. This study found extremely high error rate in the references of the Indian Journal of Surgery. Sincere effort is required on the part of authors and editorial board to improve the citations

    Does unilateral hip flexion increase the spinal anaesthetic level during combined spinal–epidural technique?

    Full text link
    Needle-through-needle combined spinal–epidural (CSE) may cause significant delay in patient positioning resulting in settling down of spinal anaesthetic and unacceptably low block level. Bilateral hip flexion has been shown to extend the spinal block by flattening lumbar lordosis. However, patients with lower limb fractures cannot flex their injured limb. This study was conducted to find out if unilateral hip flexion could extend the level of spinal anaesthesia following a prolonged CSE technique. Fifty American Society of Anesthesiologists (ASA) I/II males with unilateral femur fracture were randomly allocated to Control or Flexion groups. Needle-through-needle CSE was performed in the sitting position at L2-3 interspace and 2.6 ml 0.5% hyperbaric bupivacaine injected intrathecally. Patients were made supine 4 min after the spinal injection or later if epidural placement took longer. The Control group patients (n=25) lay supine with legs straight, whereas the Flexion group patients (n=25) had their uninjured hip and knee flexed for 5 min. Levels of sensory and motor blocks and time to epidural drug requirement were recorded. There was no significant difference in sensory levels at different time-points; maximum sensory and motor blocks; times to achieve maximum blocks; and time to epidural drug requirement in two groups. However, four patients in the Control group in contrast to none in the Flexion group required epidural drug before start of surgery. Moreover, in the Control group four patients took longer than 30 min to achieve maximum sensory block. To conclude, unilateral hip flexion did not extend the spinal anaesthetic level; however, further studies are required to explore the potential benefits of this technique

    Effect of timing of intraoperative administration of paracetamol on postoperative shivering: A randomised double-blind controlled trial

    Background and Aims: Paracetamol (PCM) has an anti-shivering effect and may also exacerbate intraoperative hypothermia. This study compares the incidence of shivering as the primary outcome and the incidence of perioperative hypothermia (<36°C) and the time to the analgesic requirement as secondary outcomes when PCM was administered after induction of anaesthesia or towards the end of surgery. Methods: In this randomised study, 225 adult patients of either gender undergoing elective surgical procedures under general anaesthesia with an expected duration of surgery of 1–4 h were studied. They received intravenous (IV) PCM 15 mg/kg (maximum 1 g) immediately after anaesthesia induction (Early PCM group), 30 min before completion of surgery (Late PCM group) or no PCM (Control group). IV morphine 0.1 mg/kg was administered for analgesia in all three groups. The Chi-square test and repeated measures analysis of variance followed by Tukey's test were used for statistical analysis. Results: The incidence of shivering was lower in Late PCM (12%) than in Early PCM (29.3%) (P = 0.009) and Control groups (30.6%) (P = 0.005). The incidence of postoperative hypothermia was also significantly lower in the Late PCM group than in the Early PCM (P = 0.002) and Control groups (P = 0.016). Early PCM and Control groups did not significantly differ. The number of patients requiring postoperative analgesia was smaller, and the time to the analgesic requirement was longer in Late PCM compared to other groups. Conclusion: Administration of IV PCM 30 min before completion of surgery results in a lower incidence of postoperative shivering and hypothermia when compared to PCM administered after induction of anaesthesia or no PCM

    Clonidine as an adjuvant to hyperbaric bupivacaine for spinal anesthesia in elderly patients undergoing lower limb orthopedic surgeries

    Full text link
    Background: In elderly patients, use of adjuvant with small doses of local anesthetics is a preferred technique for spinal anesthesia for lower limb surgeries. This study tested the hypothesis that addition of small doses of clonidine augments the spinal block levels produced by hyperbaric bupivacaine in elderly without affecting the side-effects if any of clonidine in these patients. Materials and Methods: This was a prospective, randomized, double-blind study. Above 60 years male patients were allocated to three equal groups. Group C received 9 mg hyperbaric bupivacaine without clonidine while Group C 15 and Group C 30 received 15 μg and 30 μg clonidine with hyperbaric bupivacaine respectively for spinal anesthesia. Effect of clonidine on sensory block levels was the primary study outcome measure. Motor blockade and hemodynamic parameters were also studied. Results: A significantly higher median block levels were achieved in Group C 15 (P < 0.001) and Group C 30 (P = 0.015) than Group C. Highest median sensory block level, the mean times for sensory regression to T 12 level and motor block regression were statistically significant between Groups C 15 and C and between Groups C 30 and C. On comparison of fall in systolic blood pressure trends, there was no significant difference in the clonidine groups as compared with the control group. Conclusions: In elderly patients, clonidine when used intrathecally in doses of 15 μg or 30 μg with bupivacaine, significantly potentiated the sensory block levels and duration of analgesia without affecting the trend of systolic blood pressure as compared to bupivacaine alone. Clonidine in doses of 30 μg however facilitated the ascent of sensory level block to unexpectedly higher dermatomes for a longer time
